Title: Permanent expandable intraluminal tubular stent
Inventor: AL-SAADON KHALID
IPC: A61F2/915
Filed: 1999-05-25
Abstract: A permanent expandable intraluminal tubular stent supporting device intended to maintain the walls of anatomical body channels or vessels, the stent being expandable within the vessel by an angioplasty balloon associated with a catheter thereby dilating and expanding the lumen of a vessel. The stent comprises an arrangement of connecting members interconnected by a plurality of radially expandable, elongatable members. Upon inflation of the balloon, the stent expands in both radial and longitudinal directions in relation to the amount of radially-outwardly directed force by the balloon.

Inventor: HAN MING HUI
IPC: F24F13/04
Filed: 1999-06-02
Abstract: An air mixer for an air distribution system for a building includes a set of fixed, substantially parallel partitions arranged in a spaced-apart, side- by--side manner, these partitions forming alternating primary and secondary air passageways. The primary air passageways are open-ended and extend from a front side to a rear side of the mixer. Front end plates extend respectively across front sides of the secondary air passageways and each has elongate edge portions extending along two opposite longitudinal edges thereof. Each elongate edge portion projects beyond the plane defined by an adjacent one of the partitions. Air flow splitters are mounted in the secondary air passageways and each is connected to an adjacent pair of the partitions. These splitters in operation of the mixer turn incoming air flow that enters the secondary air passageways towards the front end plates. Air gaps are formed between the elongate edge portions and front edges of the partitions to enable the air flow in the secondary air passageways to enter the primary passageways where the two air flows are mixed.

Patent CA-2278003-A1 (CA)
Inventor: SULZER GERALD M
IPC: C07F9/22
Filed: 1998-01-21
Abstract: Continuously fed to and mixed in a first reactor are: (i) a preformed mixture of primary hydrocarbyl monoamine, tertiary amine and liquid inert organic solvent, and (ii) thiophosphoryl chloride while removing heat of reaction to maintain the reaction temperature in the range of -20 ~C to +50 ~C. A reaction mixture containing N-hydrocarbylaminothiophosphoryl dichloride is formed.  Ammonia and an effluent stream from the first reactor are continuously fed to and mixed in a second reactor in proportions of at least 16 moles of ammonia per mole of N-hydrocarbylaminothiophosphoryl dichloride that produce a reaction mixture containing N-hydrocarbylthiophosphoric triamide, and that keep in solution ammonium chloride co-product formed in the reaction. Heat of reaction is removed so that the temperature is high enough to keep ammonium chloride-ammonia complex from forming a solid phase in this reaction mixture, but low enough to avoid significant reduction in yield of N-hydrocarbyl-thiophosphoric triamide being formed. Effluent is withdrawn from the second reactor so as to maintain a substantially constant volume of reaction mixture in the second reactor. The process eliminates a difficult filtration of the co-product ammonium chloride formed in the second reaction. Also, it is possible to accomplish this in a continuous process, with improved efficiency in large scale production of the N-hydrocarbylthiophosphoric triamides. Moreover, the ammonium chloride can be readily converted in the process to an industrially useful liquid co-product mixture.

Title: Ferrule-type fitting for sealing an electrical conduit in a wellhead barrier
Inventor: MOORE BOYD B
IPC: H01R13/533
Filed: 1993-04-29
Abstract: The present invention relates to a ferrule-type fitting for forming a fluid-tight seal between an insulated electrical conductor extending from outside a well to a wellhead barrier and a rigid tube that projects outside the wellhead barrier. The rigid tube surrounds the electrical conductor and extends through the wellhead barrier for routing the electrical conductor. The ferrule-type fitting is comprised of a tubular body fitting with an elongated opening sized and shaped to fit around the rigid tube. The opening includes a conical counter bored section adjacent to one end for forming a gap between the body fitting and the rigid tube. The body fitting includes an outer threaded surface on the one end. A ring shaped ferrule bushing is formed of a material softer than the material of the rigid tube, which has the tendency of returning to its original shape after being deformed. The ferrule bushing is sized and shaped to fit around and directly contact the rigid tube and interface the conical counter bore section with the gap. A nut fitting is provided which includes a threaded inner surface for engagement with the outer threaded surface of the body fitting. The nut has a shoulder for engaging the ferrule bushing. The shoulder engages the ferrule bushing so that the ferrule bushing is deformed to engage and crimp the rigid tube. This provides a fluid-tight seal between the inner surface of the rigid tube and the insulated electrical conductor after the nut fitting is tightened onto the body fitting. The ferrule bushing is not hard enough to permanently engage the rigid tube, but returns to its original shape so that it can be removed from the crimped rigid tube when the nut fitting is loosened and removed from the body fitting.
